General Definitions

Time is the rate at which change occurs in the universe. Time is incremental, continuous, and unidirectional.

Time is the absolute rate at which a change occurs, and refers to the observed rates of change of one event in relation to another event.

The time rate of change of an event or events is expressed as a length, a direction, an order, an interval, a relation, a unit, and a comparison.


Do not wait for life. Do not long for it. Be aware, always and at every moment, that the miracle is in the here and now. – Marcel Proust
